Perceived eating norms and children's eating behaviour: an informational social influence account.

open access articleThere is initial evidence that beliefs about the eating behaviour of others (perceived eating norms) can influence children's vegetable consumption, but little research has examined the mechanisms explaining this effect. In two studies we aimed to replicate the effect that perceived eating norms have on children's vegetable consumption, and to explore mechanisms which may underlie the influence of perceived eating norms on children's vegetable consumption. Study 1 investigated whether children follow perceived eating norms due to a desire to maintain personal feelings of social acceptance. Study 2 investigated whether perceived eating norms influence eating behaviour because eating norms provide information which can remove uncertainty about how to behave. Across both studies children were exposed to vegetable consumption information of other children and their vegetable consumption was examined. In both studies children were influenced by perceived eating norms, eating more when led to believe others had eaten a large amount compared to when led to believe others had eaten no vegetables. In Study 1, children were influenced by a perceived eating norm regardless of whether they felt sure or unsure that other children accepted them. In Study 2, children were most influenced by a perceived eating norm if they were eating in a novel context in which it may have been uncertain how to behave, as opposed to an eating context that children had already encountered. Perceived eating norms may influence children's eating behaviour by removing uncertainty about how to behave, otherwise known as informational social influence

Perceived eating norms and vegetable consumption in children

open access articleBackground Beliefs about the eating behaviour of others (perceived eating norms) have been shown to influence eating behaviour in adults, but no research has examined whether young children are motivated by perceived eating norms. Findings Here we investigated the effect on vegetable intake of exposing children to information about the vegetable intake of other children. One hundred and forty three children aged 6–11 years old took part in a between-subjects experiment. Children were exposed to information suggesting that other children had eaten a large amount of carrots, no carrots, or control information. Children ate more carrots when they believed that other children had eaten a large amount of carrots, compared to all other conditions. Conclusions Perceived eating norms can influence vegetable intake in young children and making use of eating norms to promote healthier eating in children warrants investigation

AN ANALYSIS OF THE CAREER PROGRESSION OF FIRST-TERM NAVY ENLISTED WOMEN

In this thesis, I analyze both pre-accession and post-accession characteristics of enlisted personnel in the Navy and evaluate how these traits specifically affect the career progression of enlisted women. To measure career progression, I use attrition, reenlistment, and promotion as observable outcomes. Using longitudinal files of personnel data on Navy enlisted personnel from accession until 2013, or until they separated, I estimate multivariate regression models to examine any differences in outcome between women and men. I find that pre- and post-accession characteristics do not explain away the gender differences in first-term attrition and retention. However, pre- and post-accession characteristics help explain part of the gender differences in fast-track promotion. Overall, enlisted women are more likely to separate from the Navy before the conclusion of their first-term enlistment contract compared to enlisted men. However, among those who do not attrite, they are more likely to remain on active duty at least three months past their initial four-year obligation. Finally, among E4 personnel, enlisted women are less likely to promote to the rank of E5 in less than four years compared to enlisted men. These findings support further research on potential factors that might explain the gender gap in the Navy.Lieutenant, United States NavyApproved for public release. Distribution is unlimited

Political masculinities, crisis tendencies, and social transition: Toward an understanding of change

This introduction to the special issue on “Political Masculinities and Social Transition” rethinks the notion of “crisis in masculinity” and points to its weaknesses, such as cyclical patterns and chronicity. Rather than viewing key moments in history as points of rupture, we understand social change as encompassing ongoing transitions marked by a “fluid nature” (Montecinos 2017, 2). In line with this, the contributions examine how political masculinities are implicated within a wide range of social transitions, such as nation building after war, the founding of a new political party in response to an economic crisis, an “authoritarian relapse” of a democracy, attempts at changing society through terrorism, rapid industrialization as well as peace building in conflict areas. Building on Starck and Sauer’s definition of “political masculinities” we suggest applying the concept to instances in which power is explicitly either being (re)produced or challenged. We distinguish between political masculinities that are more readily identified as such (e.g., professional politicians) and less readily identified political masculinities (e.g., citizens), emphasizing how these interact with each other. We ask whether there is a discernible trajectory in the characteristics of political masculinities brought about by social transition that can be confirmed across cultures. The contributors’ findings indicate that these political masculinities can contribute to different kinds of change that either maintain the status quo, are progressive, retrogressive, or a mixture of these. Revolutionary transitions, it seems, often promote the adherence to traditional forms of political masculinity, whereas more reformatory transition leaves discursive spaces for argument

Examining evidence for behavioural mimicry of parental eating by adolescent females. An observational study

Behavioural mimicry is a potential mechanism explaining why adolescents appear to be influenced by their parents' eating behaviour. In the current study we examined whether there is evidence that adolescent females mimic their parents when eating. Videos of thirty-eight parent and female adolescent dyads eating a lunchtime meal together were examined. We tested whether a parent placing a food item into their mouth was associated with an increased likelihood that their adolescent child would place any food item (non-specific mimicry) or the same item (specific mimicry) in their mouth at three different time frames, namely, during the same second or within the next fifteen seconds (+15), five seconds (+5) or two second (+2) period. Parents and adolescents' overall food intake was positively correlated, whereby a parent eating a larger amount of food was associated with the adolescent eating a larger meal. Across all of the three time frames adolescents were more likely to place a food item in their mouth if their parent had recently placed that same food item in their mouth (specific food item mimicry); however, there was no evidence of non-specific mimicry. This observational study suggests that when eating in a social context there is evidence that adolescent females may mimic their parental eating behaviour, selecting and eating more of a food item if their parent has just started to eat that food.</p

Ethical, legal and social issues in diversifying genomic data: literature review and synthesis

Advances in technology have resulted in the ability to sequence entire human genomes as a routine, relatively inexpensive, investigation in healthcare. This offers many promises of personalising, stratifying, and targeting healthcare with an understanding of genetic susceptibility to particular diseases or conditions. However, research collections (databases, biobanks etc) that underpin these developments are significantly skewed towards populations of European ancestry meaning that our understanding of genetic susceptibility (or indeed of genetic protection to disease) is less good for many other populations in the world. Just as a dermatology text book skewed towards skin problems on white skin may be less useful to black populations, so genomic knowledge derived from one particular ancestry means it may be less useful to people with different ancestries. The need to diversify genomic data, to improve the evidence base for genomic medicine for all ancestries, is well recognised, but is more complex than simply increasing the collection of data from people from a range of ancestries. We reviewed the literature to understand the challenges of diversifying genomic data to identify key ethical, legal and social issues. Our findings were: 1. Many research practices are exclusionary and need to change. Examples include approaches to recruitment or data collection that do not consider the cultural setting in which potential participants are situated. Research also often lacks reflexivity about diversity on the part of researchers and research institutions. 2. Co-design is key to identifying and avoiding potential problems around data diversification. This requires an understanding of the concerns of underserved individuals and communities regarding exploitation and stigmatisation, as well as issues of data ownership and sovereignty. Without attention to group as well as individual concerns, participant engagement may become tokenistic which in turn risks exacerbating existing, as well as creating new, inequalities. 3. There are wider structural issues that influence researchers’ and participants’ attempts to generate diverse data. For example, (a) some researchers view data as neutral, but this ignores the social construction of data and technologies, and their tendencies to reflect societal inequalities. (b). Efforts to diversify data should be contextualised within the historical trajectory of structural racism and legacies of colonialism. (c) Classification and categorisation of populations have political consequences and need to be closely interrogated. These findings show that deliberation between researchers and participants, during all stages of research from planning and recruitment through to analysis, interpretation and dissemination is key to successful diversification

Disease risk analysis in sea turtles: a baseline study to inform conservation efforts

The impact of a range of different threats has resulted in the listing of six out of seven sea turtle species on the IUCN Red List of endangered species. Disease risk analysis (DRA) tools are designed to provide objective, repeatable and documented assessment of the disease risks for a population and measures to reduce these risks through management options. To the best of our knowledge, DRAs have not previously been published for sea turtles, although disease is reported to contribute to sea turtle population decline. Here, a comprehensive list of health hazards is provided for all seven species of sea turtles. The possible risk these hazards pose to the health of sea turtles were assessed and “One Health” aspects of interacting with sea turtles were also investigated. The risk assessment was undertaken in collaboration with more than 30 experts in the field including veterinarians, microbiologists, social scientists, epidemiologists and stakeholders, in the form of two international workshops and one local workshop. The general finding of the DRA was the distinct lack of knowledge regarding a link between the presence of pathogens and diseases manifestation in sea turtles. A higher rate of disease in immunocompromised individuals was repeatedly reported and a possible link between immunosuppression and environmental contaminants as a result of anthropogenic influences was suggested. Society based conservation initiatives and as a result the cultural and social aspect of interacting with sea turtles appeared to need more attention and research. A risk management workshop was carried out to acquire the insights of local policy makers about management options for the risks relevant to Queensland and the options were evaluated considering their feasibility and effectiveness. The sea turtle DRA presented here, is a structured guide for future risk assessments to be used in specific scenarios such as translocation and head-starting programs
